PLASTIC COMPOSITION.

No Drawing.

To all whom it may concern Be it known that I, IVALTER T. FnLs, a citizen of the United States, residing at Mount Vernon, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Plastic. Compositions, of which the following is a specification.

The present invention relates to plastic compositions, such as used for building purposes for the interior or exterior finish of sition comprises the ingredients, as follows I Locomotive ashes 60% PlasterParis 30% Lime 9% Glue 1% Such materials are tho-roughly mixed and are moistened with water sufliciently to render the mass homogeneous. Such proportions are approximate, inasmuch as they can be varied somewhat, but by adhering to such proportions substantially as given, the resultant product is a thoroughly eflicient and useful one.

The glue used is prepared by cooking a suitable quantity of any preferred glue about 24 hours in plenty of water and lime amounting to about 10%, by volume, of the glue. Such solution, when boiled for about one I Specification of Letters Patent. Patented J 1 119, 13, 1922,

day, will form an effective glue to be used in mixing the composition and making the same solid when it sets. The ingredients are preferably measured by volume, although the proportions will be substantially the same if measured by weight.

After the ingredients are mixed and worked thoroughly, the material can be worked or molded into boards, sheets or slabs of suitable size and thickness and when the material has set or become dry, it can be cut into pieces and nailed or otherwise fastened to the studding or the like, to take the place of lathing and plaster or mortar, with a considerable saving in cost. The locomotive ashes can be obtained at small expense, being a waste product and constituting a greater portion of thecomposition. Inasmuch as the boards or slabs can be readily cut and nailed or otherwise fastened to the studding, this provides for a considerable saving, as over the old method of applying lathing and plaster. Furthermore, the boards or slabs are strong and durable, and also serveas sound-insulation, inasmuch as the use of the ashes will deaden the transmission of sound through the boards or slabs.

The locomotive ashes are specially desirable and efficient, although there may be other ashes or cinders which would sufiice under certain conditions.

Having thus described the invention, what is claimed as new is :r

1. A plastic composition comprising in approximate proportion, 60% ashes, 30% plaster Paris, 9% lime and 1% glue.

2. A plastic composition comprising in approximate proportion, 60% locomotive aihes, 30% plaster Paris, 9% lime and 1% g ue.
